CERAMBYCIDAE. 331 



Spalacopsis occurs in Florida and Texas ; Eulheia\\ Guer., 

 Eulhuorus Duval, was e.stablisiied upon a Cuban species, difi'er- 

 ing from ours by the aiitenntc niucli more hairy, and the scape 

 somewhat longer. These differences do not seem to be generic, 

 llippopsis is represented by one species iu the Atlantic region, 

 and Sicyobius by one in Kansas. 



Tribe XIV.— SAPERDIIVI. 



Insects of cylindrical form, of large or medium size, with large, 

 fliit, quadrate, vertical front, coriaceous labral support, and finely 

 granulated, deeply emarginate eyes. The palpi are less slender 

 than in the Acanthoderoid series, the last joint more or less oval, 

 truncate at tip. The antennie are as long as the body, or a little 

 shorter; the scape is nearly cylindrical, a little shorter than the 

 3d joint, without ai)icivl cicatrix; the outer joints scarcely diminish 

 in length. The })rothorax is cylindrical, entirely unarmed, and 

 without tubercles ; the elytra are wider than the prothorax, 

 cylindrical, usually rounded at tip, rarely (calcarala) the suture 

 is armed with a si^ine, or (obliqua) the tip is attenuated and acu- 

 minate. 



The front coxa? are angulated externally with distinct trochantin, 

 and closed behind ; the middle coxal cavities are angulated, open 

 externally, with distinct trochantin. The prosternum is very 

 narrow between the coxae, and the. mesosternuni acute behind. 

 The side pieces of the metasternum are very broad in front, and 

 narrowed behind ; a character not seen in the preceding tribes. 

 The ventral segments are nearly equal, the 5th somewhat longer, 

 somewhat truncate (9) or emarginate {%). Legs moderate, 

 nearly equal, thighs not clavate, middle tibiie without tubercle 

 or sinus; hind tarsi with 1st joint not much elongated; last joint 

 rather short in general, claws divaricate; the inner one of th(? 

 front and middle pair in the % of most of our species armed with 

 a rounded lobe or tooth, which is wanting in S. moesfa, and con- 

 color, and in the European species. 



The genus Saperda alone is represented in our fauna. Thus 

 fai', none have been found on the Pacific slope, except S. moesfa, 

 a northern species, which extends from Canada to Oregon. 



Some of the species are very destructive to cultivated trees, 

 boring into the wood, or destroying the subcortical tissues of the 

 roots.
